swift open website with a webview

Question

My first app with swift... failing terribly.

I'm trying to open a website using webview and found this code online.

class ViewController: UIViewController {
@IBOutlet var webView: UIWebView!

override func viewDidLoad() {
    super.viewDidLoad()
    let url = NSURL(string: "http://www.sourcefreeze.com")
    let request = NSURLRequest(URL: url!)
    webView.loadRequest(request)
}

Well I get a fatal error: unexpectedly found nil while unwrapping an Optional value

Why should this value be null ?!

One of two things may be going on.

Your webView is not hooked up to a storyboard element.
Your URL object isn't be initialized

I think it's the former, but I've taken the liberty of making your code safer by optionally binding your NSURL object.

class ViewController: UIViewController {

    @IBOutlet var webView: UIWebView!

    override func viewDidLoad() {
        super.viewDidLoad()

        if let url = NSURL(string: "http://www.sourcefreeze.com") {
            let request = NSURLRequest(URL: url)
            webView.loadRequest(request)
        }
}

Is your webView hooked up in the interface builder? – ArtSabintsev Jun 16 '16 at 17:54 — ArtSabintsev, Jun 16 '16 at 17:54

Change webView.loadRequest(request) to webView?.loadRequest(request).

You need to unblock Transport Security which doesn't allow http loads. Try this.

Check the updated answer. And as the other answer says, I don't think you've hooked up the @IBOutlet property in your storyboard. – Mtoklitz113 Jun 16 '16 at 16:58
